Is a hammer ruining carpentry because some people hit their thumbs? The claim that user reviews ruin entertainment is fragile—it assumes an audience too weak to think for itself.
Here's the real point: aggregators like Rotten Tomatoes spread power across thousands of voices instead of concentrating it in a few gatekeepers. That's antifragile. A single critic's bad review used to sink a film; now it's just one data point among many. Regular viewers have skin in the game—they paid for tickets, not a paycheck. The noise you call ruin is actually a stress test that separates durable art from fragile hype.
